Another 997tt clutch question
#46
So many options and I am really not in the mood to drop the engine and change clutches and setups 6 times to get what I want. I do not like the feel of the clutch, but where it engages irritates me more. I was told it was put high like that so track cars can shift faster without having to push the clutch all the way in. I guess it makes sense, you only have to push it 1/3 to 1/2 the way in to disengage and shift. My car is a daily driver, not a track car. Never driven a car that engaged this high up, with literally no free play on the back end, maybe 1/2 and inch. I guess I could try the EVOM kit, at least I can put it back to stock without dropping the engine, but it will do nothing for the engagement point.

There are other components in the clutch mechanism that effect the pedal engagement. A wearing throw out bearing fork and wearing throw out bearing pads will effect the engagement point (higher). A new throw out bearing installed on a worn fork will accelerate the wear process. Some techs will forget to lube the fork pads. Jambed of missing needle bearings will cause a high and limited engagement. A failing slave will also cause these issues.

Well, we have a plan. My Porsche guy is going to fix the hose, then drive it and see what he thinks is the best way to go to address my issues. Hopefully I will get some feedback this afternoon.

996pp, kinda wondering the same thing. I believe a true GT2 setup that the fork is on the other side. Guys have had great luck with the EVOM kit, and drilling/tapping. BUT, what is the benefit of drilling and tapping over the EVOM bracket other than the fork being on the opposite side? Just curious, want to get the best setup possible. I do know the EVOM kit can be done with the engine in, but drilling and tapping, it has to come out. Also, read a few people have screwed up the drill and tap and it was not straight.

Just joined, but have lurked for years. On my 4th Porsche, 997tt. Still have my 997.2 Carrera, which has been my daily driver this summer. So, 997tt comes in, I have read every damn thread on it I could find, and EVERYONE said you will stall it when you first drive it. So, being the badass that I thought I was, I jumped in, started her up, revved it up, let out the clutch and stalled the crap put of it. Well, so goes that. The clutches are so different. 997.2 engages about an inch or two off the floorboard, 997tt, about 10 inches. Mine has a 2.5 Sachs clutch. I really like my 997.2 better. The 997 hydraulic makes it shift like a dump truck.
Anyway, the reason for the post. I have read so much on clutches from Gt2 slaves, to lengthening the shaft, to, well, all kind of crazy stuff. I can deal with it if I can get it to engage off the floor like the 997.2. BUT, while I have read many posts saying that lengthening the shaft will do it, I have read just as many that say the hydraulic clutch wont let you even if you lengthen the shaft. Clutch is fine, stalls like a biatch in 6th, does not slip.
I do like the idea of the GT2 setup as it feels more like the 997.2, but right now my issue is clutch engagement length. So, has anyone been able to get the clutch to engage a few inches off the floor board and if so, what did you do?
Thanks, looking forward to being on this board!!!

Just bought my 997.1 TT two weeks ago...first time I ever sat in a Porsche was when I drove it off the dealers lot. I haven't stalled her yet...I think it goes back to my youth road racing the TZ250...if you could get that thing off the line without stalling it, every other internal combustion clutched vehicle is a breeze. BTW, I have also read the posts about the clutch...to me all clutches/transmissions/gear ratios are different and I really like the 997.1 TT clutch and transmission (though I would ask for a taller 1st gear)...you have to learn to drive what you are in/on.
